 The word “impfen” (German word for vaccines) spelled out using dice with individual letters, arranged on a vaccination certificate
According to estimates by the World Health Organization (WHO), vaccinations have saved more than 150 million lives over the past 50 years. However, their development would not have been possible without the use of animal testing. On April 24, these two topics converge: This day marks both World Laboratory Animal Day and the start of the WHO’s World Immunization Week. At the Helmholtz Centre for Infection Research (HZI), researchers in the project ENDURIVAC are developing an innovative vaccine technology that could eliminate the need for boosters in the long term. In their research, they also use animal testing to assess the vaccine’s efficacy and safety.
